MillimeterLectrosonics adds three models to the popular SM line
Feb 14, 2006 9:45 AM
High-end wireless technology manufacturer Lectrosonics is unveiling three new additions to the SM Super Mini transmitter line at NAB 2006, at booth #3225. Introduced at NAB 2005, the SM transmitter reigns as one of world's smallest professional audio wireless transmitters.
Right from the starting gate, the SM transmitter filled a niche for users who wanted an incredibly high-powered, cost-effective, advanced wireless transmitter in a remarkably tiny and splash-proof package.
The first of the three new additions to the SM family is the SMD (SM-Dual) transmitter that uses two AA batteries and therefore doubles the battery life of the original unit. Next is the SMQ (SM "Quarter Watt") transmitter, which has been designed to deliver 250mW power for longer range and greater resistance to interference than the standard SM (100mW transmitter) – also using two AA batteries.
Finally the RM (Remote unit) was created for programming and operation of the SM transmitter family, including the new SMD and SMQ units. The RM communicates with the transmitter via a proprietary audio signal through the transmitter's microphone, so it does not rely on line of sight, as do infrared systems. This allows the transmitter to be buried in a costume and still respond to commands updating operating frequency, audio level, sleep, control surface lockout, etc. The RM is supplied with a lanyard and quick-release mechanism for ease of deployment in the field.
The key features of the SM transmitters include their ability to function in the Digital Hybrid mode, without the hindrance of an analog compandor in the signal chain or the headroom limiting pre- and de-emphasis found in many other systems. Delivering 107dB signal-to-noise ratio and flat frequency response to 20kHz, Lectrosonics' patent-pending Digital Hybrid Wireless technology uses both 24-bit digital audio and analog FM signal transmission methods to encode a digital signal into a robust analog format for transmission over a UHF FM carrier. The SM's receiver captures the signal, and DSP circuitry recreates the original digital audio. This unique system represents the best of both wireless worlds: exceptional digital audio quality, combined with the spectrum efficiency and long range of highly optimized FM wireless systems.
Larry Fisher, Lectrosonics' president, is proud that his firm has effectively engineered what is arguably the smallest and highest-quality wireless transmitter for the pro audio industry. "We believe these three new additions to the SM line will only enhance this product's position in the broadcast, television, and live sound markets," noted Fisher.
